Figure 11. Phosphorylation of PLN at Thr17 is CaMKII dependent.
Skeletal muscle membrane proteins were extracted and subject to phosphorylation assays as described in Methods. A, expression of PLN, CaMKII and SERCA2 in different fractions. B, PLN and CaMKII phospho-Thr level and expression after different incubation conditions. Representative immunoblots are shown. Data are mean ± s.e.m., n = 3. †P < 0.01 versus −/−; *P < 0.001 versus +/+.
